The commercial SAPO-34 zeolite with 0.38 nm pore size and ZIF-8 particles 0.34 aperture were separately dispersed into different polymer matrix, to prepare the mixed matrix membranes (MMMs) for gas separation. situation of in influence fillers on separation performance membrane had been investigated this study. as-synthesized MMMs showed a better trade-off between permeability selectivity than ...

In this work, for the first time, carbon nanotubes (CNTs) with hydrophobic nature were used as an appropriate nanofiller to fabricate polystyrene (PS)/CNTs mixed matrix membranes (MMMs) vacuum membrane distillation (VMD) application, successfully. At first, effect of PS concentration on performance prepared was investigated. As a novelty, back neat also evaluated. Subsequently, at optimized (15...

This paper discusses different important gas permeation models such as “Maxwell”, “Bruggeman”, “Lewis-Neilson”, and “Pal” models to predict “Mixed Matrix Membranes” (MMMs) performance. The main parameter considered and discussed is the permeability of Hydrogen on Carbon Nanotubes (CNTs)-MMM. For evaluation of the theoretical models, experimental data of permeability for H2 were compa...

Polysulfone-based mixed matrix membranes (MMMs) incorporated with silica nanoparticles are a new generation material under ongoing research and development for gas separation. However, the attributes of better-performing MMM cannot be precisely studied experimental conditions. Thus, it requires an atomistic scale study to elucidate separation performance silica/polysulfone MMMs. As most work em...

Mixed-matrix membranes (MMMs) were developed by impregnating organofunctionalized nanoadditives within fouling-susceptible polysulfone matrix following the non-solvent induced phase separation (NIPS) method. The facile functionalization of nanoparticles of anatase TiO2 (nano-TiO2) by using two different organoligands, viz. Tiron and chromotropic acid, was carried out to obtain organofunctionali...

Abstract The environmental impacts of the manufacture chitosan (CS) and polymeric poly(1‐trimethylsilyl‐1‐propyne) (PTMSP) mixed‐matrix membranes (MMMs) for CO 2 separation by life cycle assessment (LCA) are compared. An ionic liquid non‐reported toxicity is used in CS to enhance mechanical strength, different fillers increase functional properties: ETS‐10, ZIF‐8, HKUST‐1, Zeolite A. Results wi...

Mixed matrix membranes (MMMs) were prepared using alumina nanoparticles and cellulose acetate phthalate (CAP) by varying concentration of nanoparticles in the range of 10 to 25wt%. The membranes were characterized by scanning electron micrograph, porosity, permeability, molecular weight cut off, contact angle, surface zeta potential, mechanical strength. Addition of nanoparticles increased the ...

Fermentations provide an alternative to fossil fuels for accessing a number of biofuel and chemical products from a variety of renewable and waste substrates. The recovery of these dilute fermentation products from the broth, however, can be incredibly energy intensive as a distillation process is generally involved and creates a barrier to commercialization. Membrane processes can provide a lo...

The aim of this work was the fabrication and the characterization of mixed matrix membranes (MMMs) for arsenic (As) removal from water. Membrane separation was combined with an adsorption process by incorporating the kaolin (KT2) Algerian natural clay in polymeric membranes. The effects of casting solution composition was explored using different amounts of polyethersufone (PES) as a polymer, p...
